Understood. I pose to you this, then. What about inventions that might occur on accident, as is often the case in real life? Would this also be restricted in the same way, that mortals simply would be unable to see the inheret value?
Yeah, that's how I would envision it, and I admit how awkward and problematic that seems. :shrug:
But then, if mortals are tricked into perceiving such a big illusion as the night sky by mortal mental stress and being physically unable to conceptualize and grasp the idea of infinite plane(t)s surrounded by void and rips in the fabric of Oblivion, then the idea of mortals being unable to conceptualize what is literally right in front of them isn't new, I guess.
EDIT: And really, while the "et'ada act as limitations on what mortals are capable of" is my personal belief, and I do think the sources I've cited and arguments I've made back it well enough, no true lore-scholar has ever looked over that hypothesis to either commend it or punch it full of holes. It might be an accurate statement. Or it might be utter drivel that someone like proweler or luagar or TWM could swipe away with a single post. I will say that I can think of nothing a mortal has created or done in TES that a god hasn't introduced into the world already in some way, shape, or form.
Also, and this is strictly curiosity, not some way of going around this, but would it be possible that the gods have conceptualized some sort of advanced firepower or some other technology and it isn't reflected in Nirn?
Potentially, though we might have seen it if it came from the Daedra (having explored SI and the Deadlands). It could certainly be possible, assuming of course that the gods neglected technology out of choice and not out of inexplicable inability.
